【摘要】 为全面了解农作物辐射诱变育种技术在我国的专利保护和技术发展情况，本文在专利数据库构建检索式获得专利文献，采用人工去噪和人工标引的方法，对我国农作物辐射诱变专利文献进行统计分析。分析结果发现，该领域专利在我国的申请量仍处于上升期，但授权率较低，为30%左右；来自安徽省的申请量最多，占申请总量的11%；来源于国外申请人的占比仅8%。辐射诱变专利应用最多的品种是水稻，占比约为12%；种子仍是普遍采用的辐射部位，γ射线是应用最多的辐射源，辐射诱变以获取突变体的专利最多。综上，本文分析了本领域的重点专利技术，并对本领域专利申请的注意事项提出建议，为育种科研技术研发和知识产权保护策略提供了有益参考。更多还原

【Abstract】 In order to understand patent protection and technical development of crop irradiation mutation breeding technology in China,this paper constructs a retrieval method to obtain patent documents,and then uses the method of eliminating irrelevant documents and indexing documents to statistically analyze patent documents of crop irradiation mutation in China. Analysis shows that the number of applications in this field in China is still on the rise,but the grant rate is low,which is about 30%. The largest number of applications came from Anhui Province,accounting for 11% of the total. The proportion of foreign applicants is only 8%. The specific variety with the most application of irradiation mutation patents is rice,accounting for about 12%. Seeds are still commonly used as irradiation sites,γ-ray is the most widely used radiation source,and most of the patents are related to irradiation mutagenesis for mutants. By analyzing the key patented technologies,and putting forward suggestions on matters that worth noticing in patent application of this field,this paper provides a useful reference for researchers to development technology and protect intellectual property.更多还原
